A Double-Blinded Randomized Controlled Trial Assessing the Efficacy of Opioid Disposal Instructions with Parental Education on Proper Opioid Disposal Rates Following Ambulatory Pediatric Urologic Surgery.

OBJECTIVES: To determine if the administration of standardized opioid disposal instructions with focused parental education improves proper disposal of leftover opioid medication among families of children undergoing ambulatory urologic surgery compared to routine postoperative instructions. METHODS: A prospective, double-blinded, single-center randomized controlled trial was conducted in children 6-18y undergoing ambulatory urology procedures between October 2021-April 2023. Patients were randomized (1:1) to receive either the Food and Drug Administration (FDA) opioid disposal best practices worksheet plus nursing parental education or routine postoperative instructions alone. All patients were prescribed acetaminophen and ibuprofen and a per-protocol rescue opioid prescription. The primary outcome was rate of proper opioid disposal at 10-14d post-procedure. Secondary outcomes included parents postoperative pain measure (PPPM) scores, numerical pain scale (NPS) scores, and weight-based opioid utilization at 48h and 10-14d. RESULTS: We randomized 104 participants (53 intervention, 51 control) with 97% (101/104) complete follow-up data at 10-14d. Patient demographics, procedural characteristics, and analgesia use were similar between groups. We observed no significant difference in proper opioid disposal rates between arms (31% intervention vs. 18% control; estimated difference in proportion 13% [95% CI, -4-29%]; p=0.1). There was no increased odds of proper disposal of leftover opioid medication at 10-14d with the intervention compared to the control (OR 2.0 [95% CI 0.8-5.1]; p=0.1). We observed no differences in PPPM scores, NPS scores, or opioid utilization at 48h or 10-14d. CONCLUSIONS: Providing formal opioid disposal instructions with parental education did not improve proper disposal of leftover opioid medication nor did it alter post-discharge opioid utilization after pediatric urologic surgery.

Healthcare costs and medical utilization patterns associated with painful and severe painful diabetic peripheral neuropathy.

PURPOSE: Painful diabetic peripheral neuropathy (DPN) is a common complication in patients with diabetes. It is associated with a poor quality of life and high costs of care. This study investigated the impact of painful DPN on healthcare costs and resource utilization. METHODS: This was a retrospective analysis of administrative claims of adult patients with diabetes (type 1 or 2) from Optum's de-identified Clinformatics® Data Mart Database. Patients were assigned to four cohorts by presence of DPN and pain severity, based on diagnoses and prescription patterns in a one-year baseline. All-cause and diabetes-associated costs were calculated for the year following the index DPN diagnosis. Risk factors associated with presence of severely painful DPN were evaluated. RESULTS: Relative to those without DPN, patients who had DPN without pain, painful DPN (PDPN), or severe PDPN incurred respective increases of $3,093, $9,349, and $20,887 in average annual all-cause costs. More than half of costs from painful/severe DPN were for prescriptions and inpatient hospitalization. Severe PDPN was associated with elevated odds of diabetic amyotrophy (OR: 8.09; 95% CI: 6.84-9.56), diabetic foot ulcers (OR: 6.54, 95% CI: 6.32-6.76), and loss of mobility (OR: 2.54, 95% CI: 2.48-2.60), among other complications. CONCLUSIONS: Painful DPN is associated with higher healthcare costs and resource utilization, and a greater risk of debilitating conditions that limit quality of life. Future research should focus on better treatment options and more aggressive pain management strategies to reduce the negative impacts of DPN.

Expert Consensus on Pediatric Urodynamics Reporting Using Modified Delphi Technique.

PURPOSE: Urodynamic testing (UDS) is an important tool in the management of pediatric lower urinary tract conditions. There have been notable efforts to standardize pediatric UDS nomenclature and technique, but no formal guidelines exist on essential elements to include in a clinical report. We sought to identify ideal structure and elements of a pediatric UDS assessment based on expert consensus. MATERIALS AND METHODS: Pediatric urologists regularly performing UDS were queried using a Delphi process. Participants were invited representing varied geographic, experience, and societal involvement. Participants underwent 3 rounds of questionnaires between November 2022 and August 2023 focusing on report organization, elements, definitions, and automated electronic health record clinical decision support. Professional billing requirements were also considered. Consensus was defined as 80% agreeing either in favor of or against a topic. Elements without consensus were discussed in subsequent rounds. RESULTS: A diverse sample of 30 providers, representing 27 institutions across 21 US states; Washington, District of Columbia; and Canada completed the study. Participants reported interpreting an average number of 5 UDS reports per week (range 1-22). The finalized consensus report identifies 93 elements that should be included in a pediatric UDS report based on applicable study conditions and findings. CONCLUSIONS: This consensus report details the key elements and structure agreed upon by an expert panel of pediatric urologists. Further standardization of documentation should aid collaboration and research for patients undergoing UDS. Based on this information, development of a standardized UDS report template using electronic health record implementation principles is underway, which will be openly available for pediatric urologists.

Percutaneous tibial neuromodulation initial therapy compliance and subsequent third-line treatment patterns.

PURPOSE: Percutaneous Tibial Neuromodulation (PTNM) is used to treat Overactive Bladder (OAB). This analysis summarizes patient adherence to PTNM treatment and examines trends of other third-line therapy use during and after PTNM. METHODS: Optum's deidentified Clinformatics® Data Mart Database (CDM) and CMS Research Identifiable Files were queried for adults with OAB symptoms and who underwent PTNM treatment (2019-2020). We evaluated the proportion of patients who completed 12 visits within 1 year, and defined patients as treatment compliant if 12 PTNM visits were completed within 12 weeks. We then identified the proportion of patients who used other third-line therapies after PTNM and stratified these patients based on their PTNM therapy compliance status. RESULTS: 2302 patients met selection criteria from CDM and 16,473 patients from CMS. The proportion of patients completing a full PTNM treatment course increased over time; from 16% at week 12% to 42% by week 52 (CDM) and 24% to 38% (CMS). Other third-line therapy use increased over time and was higher for PTNM noncompliant versus compliant patients at 52 weeks: onabotulinumtoxinA was 6.5% versus 5.7% for noncompliant versus compliant (CMS, p = 0.0661) and 6.4% versus 4.9% (CDM, p = 0.035), SNM trial procedure was 6.5% versus 2.5% (CDM, p = 0.002) and 4.2% versus 2.0% (CMS, p = 0.010). CONCLUSIONS: Most patients are noncompliant with recommended PTNM treatment regimen. Albeit low, third-line therapy was pursued more frequently by noncompliant patients. Given low compliance, the effectiveness of PTNM may be compromised. Alternative implantable technologies may be needed to assure effectiveness of neuromodulation.

Clinical patterns and implications of prescription opioid use in a pediatric population for the management of urolithiasis in the emergency room.

Extrapolations from the adult population have suggested that opioids should be avoided in the management of pediatric urolithiasis, but the literature is sparse with regards to actual practice patterns and the downstream implications. We sought to investigate the rate of oral opioid administration for children presenting to the emergency room (ER) with urolithiasis and to identify associations between opioid administration and return visits and persistent opioid use. The TriNetX Research and Diamond Networks were used for retrospective exploratory and validation analyses, respectively. Patients <18 years presenting to the emergency room with urolithiasis were stratified by the receipt of oral opioids. Propensity score matching was performed in a 1:1 fashion. Incident cases of opioid administration and risk ratios (RRs) for a return ER visit within 14 days and the presence of an opioid prescription at 6 to 12 months were calculated. Of the 4672 patients in the exploratory cohort, 11.9% were prescribed oral opioids. Matching yielded a total of 1084 patients. Opioids at the index visit were associated with an increased risk of return visits (RR 1.51, 95% CI 1.04-2.20, P = 0.03) and persistent opioid use (RR 4.00, 95% CI 2.20-7.26, P < 0.001). The validation cohort included 6524 patients, of whom 5.7% were prescribed oral opioids. Matching yielded a total of 722 patients and demonstrated that opioids were associated with an increased risk of return visits (RR 1.50, 95% CI 1.04-2.16, P = 0.03) but not persistent opioid use (RR 1.70, 95% CI 0.79-3.67, P = 0.17). We find that the opioid administration rate for pediatric urolithiasis appears reassuringly low and that opioids are associated with a greater risk of return visits and persistent use.

Effectiveness of Liposomal Bupivacaine With Bupivacaine Hydrochloride vs Bupivacaine Hydrochloride Alone as a Local Anesthetic for Children Undergoing Ambulatory Urologic Surgery: The Baby ORIOLES Randomized Clinical Trial.

PURPOSE: We sought to determine if the addition of liposomal bupivacaine to bupivacaine hydrochloride improves opioid-free rate and postoperative pain scores among children undergoing ambulatory urologic surgery. MATERIALS AND METHODS: A prospective, phase 3, single-blinded, single-center randomized trial with superiority design was conducted in children 6 to 18 years undergoing ambulatory urologic procedures between October 2021 and April 2023. Patients were randomized 1:1 to receive dorsal penile nerve block (penile procedures) or incisional infiltration with spermatic cord block (inguinal/scrotal procedures) with weight-based liposomal bupivacaine plus bupivacaine hydrochloride or bupivacaine hydrochloride alone. The primary outcome was opioid-free rate at 48 hours. Secondary outcomes included parents' postoperative pain measure scores, numerical pain scale scores, and weight-based opioid utilization at 48 hours and 10 to 14 days. RESULTS: We randomized 104 participants, with > 98% (102/104) with complete follow-up data at 48 hours and 10 to 14 days. At interim analysis, there was no significant difference in opioid-free rate at 48 hours between arms (60% in the intervention vs 62% in the control group; estimated difference in proportion -1.9% [95% CI, -20%-16%]; P = .8). We observed no increased odds of patients being opioid-free at 48 hours with the intervention compared to the control group (OR 0.96 [95% CI 0.41-2.3]; P = .9). The trial met the predetermined futility threshold for early stopping. There was no difference in parents' postoperative pain measure scores, numerical pain scale scores, or opioid utilization at 48 hours or 10 to 14 days. No difference in adverse events was observed. CONCLUSIONS: The addition of liposomal bupivacaine to bupivacaine hydrochloride did not significantly improve opioid-sparing effect or postoperative pain compared with bupivacaine hydrochloride alone among children ≥ 6 years undergoing ambulatory urologic surgery.

Infantile versus childhood posterior urethral valve diagnosis: management patterns and clinical outcomes at opposite ends of the spectrum.

BACKGROUND: Management patterns and outcomes are poorly defined in cases of late PUV diagnosis. OBJECTIVE: To compare post-ablation management and clinical outcomes of patients with infantile (<1 year) versus childhood (>5 year) PUV diagnosis to gain insight into the pathologies at opposite ends of the PUV spectrum. STUDY DESIGN: A multicenter retrospective cohort study was conducted using the TriNetX research network between 2006 and 2022. TriNetX synthesizes insurance claims and electronic medical record data for over 110 million patients from 92 healthcare organizations. We defined two cohorts: 1) The <1 year arm had an index diagnosis of PUV and cystoscopy with valve ablation within 1 year of life, 2) the >5 year arm had an index diagnosis of PUV and valve ablation after age 5. We report rates and time-to-first use of antispasmodics, alpha-blockers, CIC, bladder botox, enterocystoplasty or Mitrofanoff or secondary cutaneous vesicostomy, and CKD. RESULTS: We identified 569 patients (323 <1 year; 246 >5 year). Median age at diagnosis was 1 month (median follow-up 8 years) and 9 years (median follow-up 10 years) for the <1 year and >5 year cohorts, respectively. Following ablation, both arms were primarily managed with antispasmodics, with no difference between groups. The >5 year arm was significantly more likely to receive alpha-blockers or bladder botox. The <1 year arm was significantly more likely to be started on CIC, undergo enterocystoplasty, Mitrofanoff or secondary cutaneous vesicostomy, or renal transplantation. The <1 year arm had significantly higher rates and shorter time-to-progression to all stages of CKD. DISCUSSION: Despite higher utilization of conservative strategies among patients with a late PUV diagnosis, these patients had superior renal outcomes and low rates of progression to invasive treatments. Limitations include potential inaccuracies in medical coding as well as variations in thresholds to initiate CIC, perform surgical reconstruction, or proceed with renal transplantation at participating centers. CONCLUSIONS: These findings provide evidence that a late PUV diagnosis reflects an overall milder disease process.

Safety and Efficacy of Long-Acting Liposomal Bupivacaine Plus Bupivacaine Hydrochloride for Dorsal Penile Block During Ambulatory Pediatric Urologic Surgery.

This study evaluates the tolerability and efficacy of preoperative dorsal penile nerve block with Exparel plus bupivacaine hydrochloride in children>6 years old undergoing ambulatory urologic surgery. We demonstrate that the drug combination is well-tolerated, with appropriate analgesic efficacy in the recovery room as well as at 48-hour and 10-14 day follow-up periods. These preliminary data justify the need to perform a prospective, randomized trial comparing Exparel plus bupivacaine hydrochloride to other common local anesthetic regimens used in pediatric urologic surgery.

Influenza Vaccination Behaviour of Healthcare Workers in Switzerland: A Cross-Sectional Study.

Objectives: As no data are available regarding the influenza vaccination status of Swiss healthcare workers (HCW) in the ambulatory setting, this study aims to investigate their influenza vaccination behaviours. Methods: We conducted an online survey using a four-item, semi-structured questionnaire to assess HCWs influenza vaccination coverage and behaviour. Associations between influenza vaccination status, age and language as well as recommendation behaviour and reasons for vaccination were assessed using descriptive statistics and logistic regression analyses. Results: Of the 1057 completed questionnaires, 425 (40.2%) HCW were vaccinated and 632 (59.8%) not. 78.1% of the physicians and 47.3% pharmacists were vaccinated, compared to only 29.1% of the nurses, 24.3% pharmacy technicians and 13.0% medical practice assistants (MPA). There was a significant association between influenza vaccination status and HCW profession, age, language and how often an influenza vaccination recommendation was made. Conclusion: Demographic factors seem to influence HCWs' attitudes towards influenza vaccination, which in turn affects the prospect of them recommending the influenza vaccination. Diverse strategies might be necessary to encourage HCW to get vaccinated and hence, promote influenza vaccination.

An age-old problem or an old-age problem? A UK survey of attitudes, historical use and recommendations by healthcare professionals to use healthcare apps.

BACKGROUND: The coronavirus pandemic has exacerbated barriers to accessing face-to-face care. Consequently, the potential for digital health technologies (DHTs) to address unmet needs has gained traction. DHTs may circumvent several barriers to healthy independent living, resulting in both socioeconomic and clinical benefits. However, previous studies have demonstrated these benefits may be disproportionately realised among younger populations while excluding older people. METHODS: We performed a prospective survey using the One Poll market research platform among 2000 adults from the United Kingdom. To mitigate against self-selection bias, participants were not informed of the topic of the survey until they had completed recruitment. We compared willingness to use and historical use of health-apps, in addition to recommendations to use health-apps from healthcare professionals; comparing outcomes across all age groups, including a reference group (n = 222) of those aged 18-24. Outcomes were analysed using multivariate logistic regression and reported as odds ratios (OR) with respondent age, ethnicity, gender, and location as covariates. RESULTS: Willingness to use health-apps decreased significantly with age, reaching a minimum (OR = 0.39) among those aged 65 and over compared to the reference group of 18-24 year olds. Despite this, more than 52% of those aged 65 and over were willing to use health-apps. Functions and features most cited as useful by older populations included symptom self-monitoring and surgery recovery assistance. The likelihood of never having used a health-app also increased consistently with age, reaching a maximum among those aged 65 and over (OR = 18.3). Finally, the likelihood of being recommended health-apps by a healthcare professional decreased significantly with age, (OR = 0.09) for those aged 65 and over. In absolute terms, 33.8% of those aged 18-24, and 3.9% of those aged 65 and over were recommended health-apps by their healthcare professionals. CONCLUSION: Although absolute utilisation of health-apps decreases with age, the findings of this study suggest that the gap between those willing to use health-apps, and those being recommended health-apps by healthcare professionals increases with age. Given the increasing availability of evidence-based health-apps designed for older populations, this may result in entirely avoidable unmet needs, suggesting that more should be done by healthcare professionals to recommend health-apps to older persons who are generally positive about their use. This may result in considerable improvements in healthy and independent ageing.

Posterior urethral morphology on initial voiding cystourethrogram correlates to early renal outcomes in infants with posterior urethral valves.

INTRODUCTION: Posterior urethral valves (PUV) is a leading cause of chronic renal failure in childhood. Bladder and posterior urethral deformity in infants with PUV are highly variable on initial voiding cystourethrogram (VCUG). Some types of deformity may be more important than others in determining the severity of the condition. Identification of specific VCUG features may allow for a simple, early screening assessment for patients. OBJECTIVE: Determine whether morphologic features on the initial VCUG correlate to renal outcomes as measured by the creatinine nadir in the first year after ablation. METHODS: Children with PUV treated by primary valve ablation before 12 months old and followed >1 year were identified. Initial diagnostic VCUG was evaluated for the bladder height to width ratio (HW-B), posterior urethral height to width ratio (HW-PU), and posterior-anterior urethral ratio (PA-UR). A trabeculation grade was assigned by three pediatric urologists, and reflux was noted. Univariable analyses with chi-square and t-test were used to compare bladder and posterior urethral morphology factors among those who obtained a creatinine nadir <0.8 or ≥0.8 mg/dL in the first year after ablation. Linear regression was performed to correlate morphology values with true creatinine nadir. RESULTS: A total of 120 boys were ablated at mean age of 40.5 days (range 0-342) and followed for 5.9 years (± 3.85). Among these, 21 (17.5%) had a creatinine nadir ≥0.8 mg/dL. Mean overall HW-B and mean PA-UR were not significantly different between those with creatinine nadir <0.8 versus ≥0.8 mg/dL. Bladder trabeculation grade was not associated with creatinine nadir. For the entire cohort, only the difference in HW-PU was statistically significant between creatinine nadir groups with a much higher ratio among those with a nadir ≥0.8 (p < 0.001). Linear regression demonstrated a significant positive correlation between the HW-PU and creatinine nadir (R 2 = 0.097, p = 0.002). The presence of bilateral reflux is significantly associated with creatinine nadir ≥0.8 mg/dL (p = 0.001). DISCUSSION: We investigate for the first time the association of morphology features on the initial VCUG with renal outcome in PUV patients. Posterior urethral deformity as quantified by a higher HW-PU ratio is significantly correlated with a higher creatinine nadir, whereas measured bladder morphology metrics are not. HW-PU may be an indirect measure of the severity of obstruction in posterior urethral valves. CONCLUSION: The HW-PU appears to be a meaningful early morphologic metric for renal outcome.

Role of progressive urethral dilation and primary valve ablation in the long-term renal outcomes of small, preterm infants with posterior urethral valve.

INTRODUCTION: PUV patients managed with primary vesicostomy instead of primary valve ablation (PVA) historically are preterm, low-birth-weight (LBW) infants with inadequate urethral size. We previously described progressive urethral dilation (PUD) as an effective method of enhancing the likelihood of PVA in these infants, allowing equal access to PVA as an initial management method. OBJECTIVE: We aim to characterize renal outcomes in patients managed with PUD + PVA and compare this to outcomes with PVA alone. We also re-examine the effect of LBW and gestational age on renal outcomes in PUV with a cohort treated uniformly by PVA. METHODS: We performed retrospective review of 78 neonates with PUV treated with PVA prior to 10 weeks of age with >1 year of follow up. Before valve ablation, boys either underwent PUD (serial upsizing of a smaller bore urethral catheter to an 8Fr catheter; PUD + PVA) or non-dilation (smaller bore catheter was maintained; PVA-only). PUD + PVA versus PVA-only was compared using chi-square and t-test. Logistic regression was performed to assess the effect of PUD, preterm (<37 weeks), LBW (<2.5 kg), and other predictors on the final outcomes of CKD3+ and ESRD. RESULTS: 31 of 78 patients underwent PUD + PVA. Mean follow up was 5.2 years (SD 3.4), with no significant difference between PUD + PVA and PVA-only. The PUD + PVA group included significantly lower gestational age infants with lower birth weight and ablation weight. There was no significant effect of PUD on final CKD3+ or ESRD outcome on univariable or multivariable analysis. When adjusted for other variables, only Cr nadir >0.5 remained an independent predictor of CKD3+ (OR 41.2; p < 0.001) and ESRD (OR 18.9; p = 0.015). DISCUSSION: We previously demonstrated that PUD is an effective means to achieve PVA in small neonates who might otherwise require vesicostomy. The data herein demonstrates no significant effect of PUD on renal outcomes. In this unique cohort of newborns treated with PVA, only creatinine nadir and not gestational age or an independent predictor of outcomes. CONCLUSION: In small preterm infants who would have been excluded from PVA due to limited urethral size, PUD + PVA confers the same renal outcomes as PVA alone in larger infants. This novel data will assist in the risk-benefit analysis of using PUD before PVA in newborns diagnosed with PUV. When primary intervention is uniformly PVA, preterm birth and LBW are not independent predictors of renal outcomes.

Predicting childhood chronic kidney disease severity in infants with posterior urethral valve: a critical analysis of creatinine values in the first year of life.

BACKGROUND: Posterior urethral valve (PUV) is a leading cause of chronic kidney failure in children. Studies have shown that a creatinine nadir above historical cutoff values of 0.8 or 1.0 mg/dL correlates with worse kidney outcomes. The ability to use nadir creatinine more discriminately as a test of kidney outcomes is otherwise limited. METHODS: We performed a retrospective review of 102 infants treated with primary valve ablation prior to 1 year of age. Patient factors including creatinine at presentation (Cr-P), nadir within 6 weeks after ablation (Cr-6 W), and nadir within 1 year after ablation (Cr-1Y) were assessed as predictors of final chronic kidney disease (CKD) severity. An optimal threshold for four CKD levels was defined in incremental fashion using binary outcome with receiver operating characteristic (ROC). Multivariable logistic regression models compared Cr-P, Cr-6 W, and Cr-1Y while adjusting for patient factors. RESULTS: Boys were ablated at mean age of 36.3 days and followed for 6.6 years (± 3.7). When compared to other demographics, only creatinine remained independently predictive of CKD outcomes on multivariable analysis. ROC analysis demonstrated excellent diagnostic accuracy for Cr-6 W and Cr-1Y (p < 0.001) and acceptable accuracy for Cr-P (p < 0.005). Using the Cr-6 W and Cr-1Y models, high sensitivity and specificity creatinine nadir cutoffs were determined to predict each CKD outcome. CONCLUSIONS: The severity of childhood CKD can be predicted with high accuracy using the creatinine nadir within 6 weeks of ablation. The cutoff values described can be incorporated into a clinical setting for patient counseling and individual risk stratification.

Role of a Preoperative Catheter Regimen in Achieving Early Primary Endoscopic Valve Ablation in Neonates with Posterior Urethral Valves.

PURPOSE: Primary valve ablation is preferred to vesicostomy in the initial management of posterior urethral valves. However, some neonates have a prohibitively small urethra. We describe our experience with a preoperative urethral catheter regimen to enhance the likelihood of neonatal valve ablation. MATERIALS AND METHODS: We performed a retrospective review of 126 neonates with posterior urethral valves treated between 2003 and 2019 with valve ablation prior to 10 weeks of age. The preoperative indwelling catheter either was gradually upsized to an 8Fr (progressive urethral dilation), was not upsized (nondilated) or was initially larger bore (8Fr only). The primary outcome was the ability to perform primary ablation by neonatal resectoscope. The secondary objective was to establish the parameters for considering progressive urethral dilation as well as its associated risks. RESULTS: Overall 97% could be ablated. The progressive urethral dilation group had the lowest mean weight (p <0.001). Only a larger catheter at the time of ablation was significantly associated with feasible ablation (p <0.001) and not urethral dilation, the infant's weight or his gestational age. Progressive urethral dilation was associated with a longer duration of catheterization as well as double the rate of febrile urinary tract infections (8.5%) over the nondilated group (3.6%). CONCLUSIONS: A much higher rate of primary ablation is feasible (97%) than previously reported (82%). More important than the infant's weight is whether a 6Fr to 8Fr catheter is in place at ablation. If an initial 6Fr to 8Fr catheter cannot be placed, urethral dilation to 8Fr should be performed before attempting ablation. This is both a technique and preoperative assessment that is useful for operative planning.
